The Service Component Architecture (SCA) makes it possible to combine existing and new services based on a variety of technologies with components built using a component-based development approach. However, when asynchronous services compositions are executed, one or more errors can occur, possibly at the same time, affecting the composition's dependability. In many cases, parts of the composition...
Many of the problems found in the uses of exception handling are caused by the lack of testing and a priori design of the exceptional behavior. As a consequence, exceptions flow in unforeseen ways during the execution of a software system, causing a negative impact on reliability. This paper presents a new agile approach to test the exceptional behavior of a system. It supports developers in checking...
Recent studies have attempted to evaluate the benefits and drawbacks of using aspect-oriented programming to modularize exception handling code. In spite of their many interesting findings, these studies have not reached a consensus when it comes to the impact of aspectization on exception handler reuse. In fact, their results are sometimes in direct contradiction.In this paper we describe a study...
Most of the exceptions exert a global design impact as they tend to flow through multiple module interfaces of a software system. Exception handling mechanisms in programming languages were originally proposed to improve the robustness and comprehension of error handling code. These mechanisms are traditionally based on the fundamental assumption that global exception flows should be always implicit...
